n Application filed September 24, 1903. Seriallo. 174,44. (No model.)

To all wwnt it 711/07/ concern:

Be it known that I, FRANKLIN J. PERKINS, a citizen of the United States, residing in Woburn, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Machines for Unhairing Hides or Skins, of which the following description, in connection with the accompanying drawings, is a specifiterial is employed, which is passed about suit-*- able rollers mounted in' a substantially vertical plane on a reciprocating carriage, the said bed or apron cooperating with an operatingtool, preferably a rotatable bladed cylinder or roll, which engages the hide or skin on the said bed or apron between said rollers. The reciprocation of the carriage may be effected by power, and provision is made for causing the ie'xible bed to travel in opposite directions, so as to feed the hideinto and out of the machine at the will of the operator, as

will be described. The flexible bed has cooperating with it a feed-roll carried by a support which is pivoted to the carriage and which is automatically placed into its operative and inoperative positions with relation to the said bed, as will be described. These and other features of this invention will be pointed out in the claims at the erid of this specification.

Figure 1 is a front elevation, with parts broken away, of a machine embodying this invention; Fig. 2, aside elevation of the machine shown in Fig. 1 looking toward the right; Fig. 3, a detail in plan view, to be referred-to; Figa, a detailin section on the line 4 4, Fig. 3; Fig. 5. a detail in section on the line 5 5, Fig. 3; and Fig. 6, a'detail to be referred to.l

In the machine herein shown as embodying material,l which is arranged, as shown. to move 1n a substantially vertical path and 1s 'passed over an upper roll f and a lower roll g. mounted in boxes it z', carried by a movable support. The movable support referred to may be made as herein shown and consists of two side frames j, mounted to slide on the uprights or side pieces@ of the frame of the machine, the side frames j' being guided in their movement by rods fastened at one end, as by screws Z, to lugs or ears m on the uprights a b and having their opposite ends extended into suitable holes or sockets in extensions or arms n Aon the side frames y'.

The flexible endless'bed or apron emay be kept under proper tension in any suitable manner, and inthe present instance this result is accomplished by means of springs o, (see Fig. 2,) which act upon the lower boxes v1 to force them away from the upper boxes l, the lower boxes in this manner being made movable or yielding to permit the bed or apron to yield to compensate for uneven thicknesses in the hide or skin.

The carrier or support ,7' for the endless bed or apron c may be reciprocated by power, and for this purpose one of the side frames of the carrier or support has pivotally connected with it at` p one end of a connecting rod or is supported in the arms 12 of substantially' elbow-shaped levers 13, pivoted to the side frames of the carriage j'. and having their yother arms, 1 4, extended toward the front of The the machine and provided1 with studs or procounter-shaft 31 is connected with the shaft jections 15,' extended in-to cam slots. grooves. or channels 16 in the side frames t I), the said studs preferably having on them anti frictionrollers 17. i Thecam-slots1'6, as herein shown.' are'provided at theii` opposite ends with horizontal portions 16 19for a purpose as will bedescribed, l

on their pivots and move the feed-roll with relation to the flexible hed or apron 1. As herein shown, the feed-roll 1() is moved away from the iiexible bed or apron when the antifriction-rollers travel up thecam-slots 16 and is moved toward the said apron whenthe saidA rollers travel down the said cain-slots.

w V'y :As represented in Fig. 2, the feed-roll 10'is mounted in boxes 20, which slide in the. slots 21 ixi the end of the arms 12, and the said boxes' are :backed by suitable springs 22, arranged between the boxes 2O and caps 23 on the arms 12, which springs serve to hold the feed-roll i-n engagement with the hide or skin' withy a yielding pressure.'v The endless apron or bed e is adapted to be moved or driven in opposite directions, so as tofeed-the hide or skinv Isprocket-Wheel i28,which.is connected by a link chain 29 with a sprocket-wheelBO, loose on a counter-shaft 31. which has loose'on it a pinion32, which mesheswith the gear-wheel r and is of such size as to effect a half-revolution of the gear-Wlieel fr for each complete revolution of the pinion 32. The pinion 32 is provided with an elongated hub 34, (see Fig. 4,) to which is keyed to revolve therewith and slide thereon a'cluteh hub or member 35, which cooperates with a clutch arm or member 36, carried by the sprocket-wheel 30, to couple the pinion 32 with the said Wheel. The pinion 32 is provided with an annular flange 38 on its side or face, which flange has a slot 39 (see Fig. 5) into which a roller 40, (see Figs. 3 and 6,) carried by an arm 41, is adapted to enter, as will be described. The arm 41is fast on a rock-shaft 42, supported in suitable bearings and having a second arm 43, whiclris connected by a link 44 With a crank or arm 45on a rock-shaft 46, provided vwith a foot-treadle 47.

The sprocket-wheel 30 is adapted to be rendered fast on the counter-shaft '31 by a clutch mechanism -of any suitable construction and comprisingthe member 48, fast on the shaft and adapted to be engaged with the wheel 30 by the member 49 loose on the shaft 31.

The

25 bythe gears 50 51 52 53. The clutch hubs or members 27 49 are/connected to an operating-lever 55 on opposite sides of its pivot 56, so as to'be simultaneously moved in opposite directions. The shaft ol the upper bed-rollf is provided with a sprocket-wheel 58, which y g is connected by alink chain 59 with a sprocket- The cani-slots 16 serve to turn the levers 13 wheel 60, fast on the shaft 25.

` The'shaft of the knife-cylinder r/ has fast on it a pulley62, and the said pulley and the pulley 26 are continuously driven by separate belts. (Not shown.) The Shaft of the feedroll has fast on it a pinion 65, which engages a gear 66 on the shaft of the upper roll f w-lien the feed-roll is in its operative position shown in the drawings. By the mechanism above described the reand the endless band or bed and the feedroll 10 are moving in opposite directions (iiidicated by the arrows in Fig. 2) to feed the hide or skin (not shown) out of the machine.

With the parts in the position shown power is transmitted fiom the pulley 26 to the sprocket-wheel 30 by the link chain 29. The wheel 3() being rendered fast on the countershaft 31 rotates the latter, which in turn rotates the shaft 25 through the gears 5() 51 52 53. The shaft 25 through the link chain 59 drives the shaft of the upper roll f, which by the gears 66 65 rotates the feed-roll 10. While the machine is operating upon the hide or skin the carriage for the endless bed is stationary, the roller 4() at such time engaging the slot 39 in the flange 38 on the pinion 32. When a portion of the hide or skin exposed to the action of the bladed cylinder has been fed beyond the influence of the latter, the operator depresses the foot-treadle, thereby rocking the shaft 42 so as to withdraw the roller 40 from the slot 39 and simultaneously causing the clutch hub or member 35 to engage tlie member 36 and couple the pinion 32 with the wheel 30, thereby imparting motion to the gear-wlieel @which makes ahalf-revolution and moves the carriage toward the front of the machine.

Then the carriage has reached the front of the machine, the pinion 32 is unclutclied from the wheel 30 by the roller 40 again entering the slot 39 in the iiange 38, the operator in the meantime having removed his foot from the treadle. rlhe carriage remains stationary at the front of the machine, and the operator is free to reverse the hide or skin or to place substantially one-half of a fresh hide or skin over the endless bed andv between it and the feed-roll 10, which latter has been turned back away from the endless bed or apron by the cam-slots 16 on the forward movement of the IIO carriage-7 The feedroll is held in lits open position the horizontal portion 1;8 of the. clllrslot. f yThe treadle is'- again depressed,`

whichclutches the l pinionlljwith the wheel knife-cylinder Z the carriage is stopped by the roller 40 entering the slot V39 inthe iiange 38 on the pinion 32. 1 v- During the movement of the carriage towardthe operating tool or cylinder the feed-roll 10 is moved upward by the rollers traveling down the cam-slots 16, and when the rollers are in the horizontal portions 19 of "the camslots the feedfroll is above and substantially in a vertical line with the rolls carrying'fthe end-r less bed or apron. .The portion of the hide or skin between the endless bed` and the knife,- cylindergis acted upon by the saidknife-cylinder as the hide or skin is fed forward or out of the machine. Insome. instances it may be desirable to lsubject the hide or skin to a second operation without moving the carriage from its operative position shown in Fig. 2, and this result may be accomplished as herein, shown, by moving the lever so as toidisengage the clutch-hub 49 from the member 48, and thereby unclutch the wheel 30 from the shaft 31, and to engage'thc clutchhub 27 with the ymember;` 72, and thereby clutch the pulley 26 Ito the shaft 25. c In this case the i shaft 25 is driven directly from the, pulley Qfand is rotated in a-reverse direc- 4`tionto 'that' in whichit is driven from the, counter-shaft 31, thereby causing the bed-supv porting roll f and the 4feed-roll `1Oto be rotated in the reverse direction, so as to feed thehide orskin into the machine, and when said hide or skin has been fed into the .ma-

chine suiiiciently `far the operator reverses the' lever 55-that is, moves the same into the position shown in Fig. 3-and 'causes the hide or skin to be fed out ofthe machine.

The lever 55 maybe moved in opposite directions in vany suitable manner, and in the present instance I have shown a shipper-rope as attachedto the lever 55 and passed under guide-pulleys 81. In practice the shipperrope will pass overa second set of pulleys, (not shown, but which are located above the pulleys 81 and supported in any suitable manner.)

Theroller 40 may` be operated by gravity.

' as herein shown, to cause it to enter the slots in the flange 38.
